INVERSE MULTIPLEXING OVER ATM
• UTOPIA L2 receive slave can also appear as a single port with the logical port
provided as a prepend or in the HEC/UDF field.
• ATM transmit interface supports 8- and 16-bit UTOPIA L2 and Any-PHY cell
interfaces at clock rates up to 52 MHz.
• Each link configured for cell delineation or each IMA group appears as a PHY
port on the Any-PHY and UTOPIA L2 bus.
• Any-PHY transmit slave appears as an 8-port multi-PHY. The PHY-ID of each
cell is identified in the in-band address.
• UTOPIA L2 transmit slave appears as an 8-port multi-PHY.
• Seamlessly interconnects to PMC-Sierra’s PM7326 S/UNI-APEX ATM/Packet
Traffic Manager and Switch and PM7324 S/UNI-ATLAS ATM layer device.
Loopback and Diagnostic Features
• Supports UTOPIA L2/Any-PHY Loopback (global loopback– where all cells
received on the UTOPIA L2 / Any-PHY interface are looped back out)
• Supports Line Side Loopback (global loopback– where all data received on
the line side is looped back out)
• Supports the capability to trace ICP cells for any group
Software
• The S/UNI-IMA device driver, written in ANSI C, provides a well-defined
Application Programming Interface (API) for use by application software. Low
level utility functions are also provided for diagnostics and debugging
purposes. Software wrappers are used for RTOS-related functions making the
S/UNI-IMA device driver portable to any Real Time Operating System (RTOS)
and hardware environment. The S/UNI-IMA device driver is compatible
across the S/UNI-IMA family of devices.
Packaging
• Implemented in low power, 0.18 micron, 1.8V CMOS technology with TTL
compatible inputs and outputs.
